Damaged lorries lie upside-down near a collapsed section of the Yangmingtan Bridge in Harbin in northeast China's Heilongjiang province. Three people were killed and five injured when the eight-lane bridge collapsed, only nine months after it opened.
The bridge, part of an airport expressway in Harbin city, only opened last November after two years of construction that cost 1.9 billion yuan (£188 million)Picture: AP
